My criteria is low volume usage, maybe a couple of times a day tops on an admin dashboard and maybe on an analytics report.
Functioning in any environment is preferred for low maintenance reasons obviously.
I only need two basic charts ATM, a stacked bar chart and a pie chart, so the overall complexity of the library isn't a deal breaker at the moment and both pChart and Flotr2 seems to work but they both have issues.
Flotr2 has some sort of rendering problem with the legend box on stacked charts and everything is kind of washed out with the selected background color while the pie charts and others don't have this particular ailment.
Looking at some lesser known stuff but at this point I'm almost tempted to either write my own, done it before, to avoid having to debug someone else's mess and/or drop a couple of dollars on a commercial library.
Just wish Flash was still a consideration because the free FusionCharts just rocked and the Google charts were easy but didn't work on Andoid when I tried them but maybe it would in the more current browsers and I haven't retested in a while.
I'm starting to think I might just use the pChart stuff as-is in the short term since I have a functioning prototype and revisit it later when I want to add advanced functionality but I hate taking shortcuts.
